摘要
目的 探讨心电图 U 波倒置联合碎裂 QRS 波(fQRS)预测急性冠脉综合征(acute coronary syn-drome,ACS)患者经皮冠状动脉介入术(PCI)后预后的价值.方法 选取河南省直第三人民医院 2017 年 10 月—2019 年 9 月收治的 123 例 ACS患者,入院后均实施心电图检查,并接受PCI治疗,术后随访 3 个月,统计患者心电图 U波倒置、fQRS发生及预后情况,探讨心电图 U波倒置联合 fQRS对 ACS患者 PCI 后预后的预测价值.结果 123 例 ACS患者心电图 U波倒置发生率为 39.84%,fQRS 发生率为 33.33%,预后不良的发生率为 23.58%;预后不良组 U波倒置、fQRS发生率均高于预后良好组(χ2 =20.547、26.080,P<0.05);心电图 U 波倒置联合 fQRS预测 ACS患者PCI后预后不良的特异度、准确度、曲线下面积(AUC)均高于心电图 U 波倒置、fQRS单独预测(χ2= 3.291~11.132,Z=3.543、4.861,P<0.05).结论 ACS患者 PCI 后预后不良的发生风险高,心电图 U 波倒置联合 fQRS对 ACS患者PCI后预后不良有较高的预测效能.
Abstract
Objective To investigate the value of U-wave inversion combined with fragmented QRS(fQRS)on electro-cardiogram in predicting the prognosis after percutaneous coronary intervention(PCI)in patients with acute coronary syndrome(ACS).Methods A total of 123 patients with ACS admitted to The Third People's Hospital of Henan Province from October 2017 to September 2019 were included.All the patients underwent PCI after electrocardiogram examination,followed by 3 months follow-up.The percentages of U-wave inversion,fQRS,and a poor prognosis were analyzed to determine the predictive value of U-wave inversion combined with fQRS for post-PCI outcome in patients with ACS.Results Among the 123 patients with ACS,the percentages of U-wave inversion,fQRS,and a poor prognosis were 39.84%,33.33%,and 23.58%,respectively.The patients with a poor outcome showed significantly higher percentages of U-wave inversion and fQRS than those with a good outcome(χ2= 20.547,26.080,P<0.05).U-wave inversion plus fQRS showed significantly higher specificity,accuracy,and area under the curve in predicting a poor prognosis following PCI in patients with ACS,as compared with U-wave inversion and fQRS alone(χ2= 3.291-11.132,Z=3.543,4.861,P<0.05).Conclusion Patients with ACS have a high risk of a poor prognosis after PCI,which could be well predicted using U-wave inversion in combination with fQRS.
